I Application filed April 4, 1904. Serial No. 201,470. (No model.) i

To all whom it may concern.-

Beitknown that I, FRANcIs J. LYoNs, a.citijzen of the United States, residing at the city of tion, in which St. Louis, State of Missournhave invented.

. soffit-board and the hangers in operative positions. Fig. 3 is a disassociated detail perspective view of the hanger or anchor bolt, and Fig. 4 is a detail perspective view of a wrench used in connection with my invention.

This invention relates to concrete-floor construction, and particularly to means for supporting the grout or concrete in a semiplastic state previous to its being set, so that a prede termined form of the lower part of the floor or ceiling will be. preserved. Heretofore it has usuallybeen the practice to secure the soflit-board and the haunch-board by suitable wiring or sometimes by bolting the soiiitboard to the beam embedded in the concrete structure. These methods, however, have been found to be inconvenient for divers rea-j sons'for example, in wiring the soffit-board to its beam a bending-machine is necessary, and owing to the particular nature of this work considerable inconvenience was expe-v rienced in transporting the wiring-machine from place to place. In utilizing the bolts it was found necessary to cut ofl'theends thereof, so as to releasethe boards, and as a result the ends of the bolts either project through the ceiling or the ceiling would have to be pointed up to conceal theprojecting ends. By employing a construction similar to the one described hereinafter these inconveniences are avoided. 7

Referring now to the drawings by numerals of reference, 1 1 designate suitable horizontal metallic beams, preferably I-beams, which terial forming the floor.

are supported'upon suitable recesses generally in the formof a masonry wall, as indicated at 2inFig.2.

3 designates the soffitboards, and 4: the

hau'nch-board's, the latter having inclined sides connected at their upper edges by a cross-board 5. In forming the plasticfloor the soffit-iboards are suspended or supported from theI-beams, which soffit-boards in turn support the haunch-boards, the whole'form ing an eflicientfsupport for the plastic ma- In order that the soflit-boards may be conveniently supported, suitable hangers are provided which are proferably constructed as illustrated in Fig. 3, in which 6 designates the socket member and 7 the complementary member. The socket member 6 is designed to be anchored tothe flange 8, and in order that this may efficiently be accomplished I provide a projection 9 at one end thereof which is capable of embracing the upper side of the flange 8 of one of the beams. 00- operating with this projection 9 is a finor web. 10, which is provided with a plurality of serrations or shoulders 11, capable of independent contact with the bottom of one of the flanges. The purpose of having the irregular upper edge formed by the shoulders 11 is to insure a firm contact with the flange of the beam irrespective of its thickness. The web 10 is assisted by. an oppositely-disposed web 12, carried by the socket member 6 in maintaining a rigidcontact with the flange of the beam when the concrete has been flowed be-' tween the boards, so that any. liability of the socket member turning will be avoided. -Another advantage in providing the web 12 is that the edge thereof will abut against the side of the haunch-board, so that irrespective of the weight upon the soffitsboard it will be impossible for the jaw formed by the projections 9 and 10 from becoming detached from the flange of the I-beam. The cooperating 1 member 7 is provided with a threaded shank for engagement with corresponding threads in the socket member 6, and the rectangular head 13 of the member 7 is provided with a groove 14, preferably V-shaped in cross-section, so that the reduced edges 15, carried by the jaw of the wrench 16, may "firmly grasp the edges of the head 13, whereby the member 7 may be screwed into and out of contact with the member 6.

By reference to Fig. 1 the manner of assembling the parts will be clearly apparent, and after the plastic material has set it will only be necessary to remove the member 7 so that the soffit-boards may be released, which in turn will permit the haunch-boards to be released. As a result, there will be no projections ,to be cut off, and the manner of applying and removing the supporting-boards will be greatly facilitated. 1t frequently happens that a premises in which a concrete ceiling and floor is employed is partitioned after the concrete structure is formed. Heretofore the general practice has been to dig out the ceiling so that hangers can be attached to the beams, as it is desirable that the partition aline with the beams. In order that this can be done, it is usually found necessary to attach some type of hanger to the beam, so that the skeleton forming the partition and which acts as a support for the concrete composition can be suitably held in place. Inasmuch as the socket member 6 will remain embedded in the concrete structure it will only be necessary to run a bolt through a part of the skeleton frame, which bolt can be inserted in the socket, and the frame will thus be securely supported Without the necessity of digging out the concrete around the beam. Thus any liability of weakening the concrete structure will be avoided.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. A hanger for concrete structures comprising two members one of which is provided with a right-angularly-disposed projection for engagement with a support, and a headed complementary member removably secured to the first-named member; substantially as described.

2. A hanger for concrete structures having a right-angular projection at one end, and shoulders alining therewith and in different planes; substantially as described.

3. A hanger for concrete structures comprising two members, one of which is adapted sitely-disposed anchor-fins carried by theembedded member, and means for removably connecting the two members; substantially as described.

4. A hanger for concrete structures comprising two members having threaded connection, one of which is provided with a head having a groove around the periphery thereof; substantially as described.

5. A hanger for concrete structures comprising two members having threaded connection, one of which is provided with ahead having a V-shaped groove around the periphery thereof; substantially as described.

6. A hanger for concrete structures comprising two members having threaded connection, one of said members having anchor projections whereby said member can be permanently fixed in the concrete and the other member having means for removable attachment to the permanent member and provided with a head having a groove around the periphery thereof; substantially as described.

7. A hanger for concrete structures comprising two members one of which is provided with a rigid jaw for engagement with flanges of varying thicknesses, and a removable member connected thereto; substantially as described.

8. The combination with a plurality of beams, permanenthangermembers connected to the lower flanges of the beams, a sollitboard beneath the permanent members. and removable members projecting through the soflit-boards and connected to the permanent members; substantially as described.

9. A hanger for concrete structures, comprising two members one of which is provided with a right-angularly-disposed projection, a cooperating fin below the first-named projection, an anchor-fin oppositely disposed with relation to the first-named lin, and a headed member removably connected to the first named member; substantially as described.

10. A hanger for supporting a removable soffit-board for concrete structures, the same comprising an anchor member designed to be left in the concrete, said anchor member havinga jaw for engagement with a beam-flange, and another member for supporting the sollitboard in position; substantially as described.

111 testimony whereof I hereunto allix my signature, in the presence of two witnesses, this 31st day of March, 190*.
